4. Select your file from Print Files menu and press print.
5. Once the print is done the LC Magna logo will change from red to green, you can start the cleaning process (sections 3 and 4).
1. Take off the platform. Drain off excess resin by holding the platform vertically over the vat.
2. Wipe off the remaining excess resin from the platform with absorbent paper.
3.1. Place the platform in Photocentric Wash99 filled with Photocentric Resin Cleaner. Wash for 5-10 minutes.
If necessary, leave longer than 10 minutes.
Take the platform out of the wash unit and rinse with warm/hot water.
3.2. Spray warm soapy water over the parts. A sponge or soft brush can be useful to clean detailed parts. Rinse with warm/hot water.
4. Once cleaned, there should be no trace of uncured resin visible.
5. If you have access to an air compressor with an air gun, you can dry your parts after cleaning. We recommend this for delicate and accurate parts to ensure all holes and pores are free of any traces of uncured resin.
1. Gently remove the parts from the platform by sliding the scraper (provided) or a snap-off blade knife (taking great care) underneath parts.
2. Place parts under hot water (60°C) in UV light for 15 minutes to remove the surface tack.
3. Large parts can be post exposed for 1 hr in water, under UV light.
4. Once post exposure is complete, dry parts and your print is ready.
5. To prepare for the next print job, scrape off any cured resin and clean the build platform with hot water and Photocentric Resin Cleaner in the spray bottle. Dry the platform and place on the print arm.
Note: Take extra care to make sure the platform is clean and there is no residue of cured parts. Any hard resin may pierce the vat film and could cause print failure. Please see Maintain Section.
6. Pour the remaining resin from the vat back into the bottle using the funnel and filter paper provided.
7. Use the vat cleaning tool (provided) to direct any excess resin from the vat down towards the funnel.
8. Place the vat on the Foam Vat Cleaning Mat (provided) and mop up any resin residue with absorbent paper.
9. Use the soft spatula (provided) extremely carefully to remove small cured pieces.
Note: Take extra care to make sure the Cleaning Mat is perfectly clean and there are no chips of cured resin on it. If the vat film gets damaged, it can lead to a vat leak and damage to your printer.
10. Make sure your screen plate area is clean prior to placing the vat back into place on the printer.
11. If you have evidence of a leak on the screen, mop up the liquid resin immediately using absorbent paper or a damp tissue with IPA. Hardened resin can be removed by chipping off carefully with the provided soft spatula. It is extremely important to keep your screen plate surface clean from any resin. If not, you risk print and/or printer failures.
You will need to change the vat film after 6 times of use.

Tips & Tricks
Loud Beeping Noise
If you are experiencing this loud noise coming from your LC Magna then it sounds like your Magna blow peel sensors have gone off, this will have occurred due to a vat leak.
This is caused when the vat film has unexpectedly been pierced or torn and resin has passed out of the vat and onto the blow-peel system. To prevent damage to the machine the system activates sealing your blow peel system and the alarm activates to indicate that the leak has occurred.
In this event please follow the below guide:
1. DO NOT REMOVE THE VAT UNTIL PROMPTED, this will cause any resin held in the vat to no longer be retained inside the vat wall.
2. Immediately cancel the print.
3. Go to Maintain menu and use the lift platform function to ensure print platform is raised allowing full access to the vat. Remove the platform from the printer.
4. You may wish to turn off the machine, as during this process the buzzer will sound continuously. Doing so will not adversely affect the system.
5. Empty any remaining resin in the vat by scooping out resin from the vat.
6. Wipe out the vat the resin residue.
7. Carefully remove the vat from the printer.
8. Wipe any excess resin off the screen.
9. Identify which air hole has been contaminated with resin, this may be one or more of the holes.
10. Take a new pipette from accessories box and use this to remove the resin from air hole.
11. Fill the pipette with fresh IPA, apply this into the air hole and flush by squeezing and releasing the pipette.
12. Continue this until the IPA is contaminated then dispose of the contaminated IPA and repeat the process until the IPA is clear.
13. Once clear use the swab from the kit
to dry any excess IPA from the hole.
14. Once you are satisfied, turn the printer back on (if turned off) or press the reset button at the back right of the screen plate to reset the leak system. The continuous beeping noise should now have stopped and the printer is ready for use.
15. If the buzzer continues there is still contamination in the holes. Please re do the 10 -13 cleaning steps.
